well lads just got back froma rolling road set up and this is the result

179.9bhp

178of torque


mods:

superchipped ecu
pro alloy front mounted
kent cvh 35 cam
and pully
t3 hybrid with .48 exhaust
mongoose full system
-31 actuator

ok, so we ran the car and got the fueling spot on first making sure she wasnt leaning out before upping the boost , all i waas able to run was O.8BAR seems to be the actuator its screwed right up and its peaked and held 0.8 bar .....

next wee set up the cam it ran a 168 before the cam was dailed in and then it ran 179 so happy with that ...

so it made 179.9bhp on 0.8 bar of boost not bad .....just worndering why when a -31 is screwed right up did it only make 0.8 with no leaks as system was all tested for leaks and its a new actuator as well ???

 

amal valve needs rejetting (if it's working that is)

-31's lift off at 7psi. Easy thing is a 3 port bleed valve.

 

sorry i should have said ive bypassed the valve so its not even being used

 

That might be why then......

 

why? if u reconnect the valve does it up the pressure? im a bit confused i understand that u disconnect the amal valve so that ur able to run higher boost than the 9psi set by the factory ??? can someone please tell me if this is true ?

 

no fella you leave the amal valve connected and adjust the jets till you reach the desired psi hope this helps

 

Yes, it most probably will. In the end, it is nothing more than an electronically controlled bleed valve. Even in its low boost modes it bleeds a small amount of air away from the wastegate actuator.

 

right i connect the amal valve and its made no difference at all any other suggections? and ive tryed two different actuators and both the same result .... the turbo is a t3 with a 0.48 exhaust housing using a -31 ...whats could be the problem thats it only allowing 0.8 bar off boost ?

 

Maybe the actuator rod is too long?

 

Ur problem is most likely still with the amal valve. Is it it plumbed in electrically and mechanically?

 

ive it plumed in just the wee connector on it mate, but explaine this...it ran 14psi on the old t3 standard with the same actuator bit on this turbo ive it wond rite up and only 0.8bar ..and the amal valve has been the same for both turbos

 

IS it piped up correctly?

W is for the wastegate actuator
R is return to metering unit
C is for compressor housing

You may have to jet the amal valve. There is a small white plastic restrictor in one of the ports of the amal valve. You may need to open the hole up very slightly.

Make sure it is connected electrically too as the ECU will be trying to open and close it to bleed air off and increase the boost. If the ECU can't control the valve, it will remain closed and just send the air straight through to the actuator (essentially making the pipe from the compressor housing and the one from the actuator a straight peice of pipe).

 

If you can't get it to work properly with the amal valve, you may need to get hold of a 3 port manual bleed valve (Stu@ MSD has them in stock I think). RS Turbos need a 3 port one to work properly and you just replace the amal valve with it using the 3 pipes from the amal valve.

 

Best thing is to have a working amal valve AND a bleed valve in line. So ECU can still decrease boost if there's a reason for it.

 

right i understand what u are all sayig about the amal valve but its been the same on the standard t3 as it was with the hybrid t3 and i was able to run a bar or more if i wanted on the standard t3

 

unplug ur actuator pipe and go for a drive....... carefully....

 

yea was thinking of doing that rick just too see what happens lol but hoprfully not bad lol ill take it easy give it a bit in 4th and see if the boost goes over 0.8bar and if soo then ill know its my actuator ..??

 

Perhaps I expect a little too much in life but,-
Shouldn't the rolling road operator have told you what was wrong?

Also, get rid of that daft cam put a standard one in it and watch your torque jump up to 200 ftlbs at lower revs.

 

no not really tbh cos how would he really know with out spending hours trying to work it out, as for the cam its fine and works a lot better then the old one considering i had the car at 12psi -13psi and it made 151bhp and 171 of torque ,,, with the cam and the turbo(which isnt even under strain yet) it made alot more bhp but not much torque once its running more boost that will all rise
